Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.

Performance Expectation

Grade: 
Middle School (6-8)
Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.

Performance Expectation

Grade: 
Middle School (6-8)
Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.

Performance Expectation

Grade: 
Middle School (6-8)
Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.

Performance Expectation

Grade: 
Middle School (6-8)
Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.

Performance Expectation

Grade: 
Middle School (6-8)
Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.

Performance Expectation

Grade: 
Middle School (6-8)
Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

Performance Expectation

Grade: 
Middle School (6-8)
Evaluate competing design solutions for maintaining biodiversity and ecosystem services.*

Performance Expectation

Grade: 
Middle School (6-8)
Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.

Performance Expectation

Grade: 
Middle School (6-8)
Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.
